Ultraman: Card Fusion System

Su Bai wakes up in the world of Ultraman with an incredible gift—a Card Fusion System that lets him collect and merge cards of legendary Ultramen and fearsome monsters. With each fusion, his power grows beyond imagination. But as he boldly declares his ambition to become the strongest Ultraman in history, even his own system begs him to tone it down. In a universe where giants battle cosmic threats, one transmigrator is about to rewrite the rules of heroism.
